Biostratigraphy and Microfacies of Qom Formation in Urumieh – Dokhtar Zone, Iran

Abstract

Qom Formation is well developed in Urumieh-Dokhtar Zone, Iran. Three different measured sections were studied in this area in order to interpret the biostratigraphy and microfacies of QomFormation. In the Ashtian and Hezar Abad sections, the Qom Formation disconformably overlies and underlies Lower Red and Upper Red formations, respectively.In the Rakin section, the lower boundary of Qom Formation with tuffs of Urumieh-Dokhtar magmatic arc is sharp and its upper boundary is covered by the recent alluvium. Based on the recognized foraminifera, the age of Qom Formation in the Rakin stratigraphic section is determined as Chattian-Aquitanian and in the Ashtian stratigraphic section as well as the Hezar Abad stratigraphic sections is determined as Chattian. In this study 21microfacies types have been recognized which can be grouped into three depositional environments: Lagoon, shallow and deep open marine. The Qom Formation in three sections represents sedimentation inan open shelf.The great abundance of bryozoans and red algae as well as low diversity of foraminifera indicates that carbonate sediments of the Qom Formation were deposited in a mestrophy to eutrophy conditions.

Help-seeking strategies and treatment experiences among individuals diagnosed with Bipolar Spectrum Disorder in Iran: A qualitative study

“…In our study, participants in different cities and from different social backgrounds reported watching, listening to, and reading pop-psychology lectures given by Iranian psychologists in the diaspora (such as radio and TV shows by Dr. Holakouee 4 and Dr. Farnoody 5 ) as well as reading selfhelp lessons (mostly through social media and satellite TV programs) as common pathways to understand their psychological and interpersonal difficulties and obtain advice. In their live audio and video programs (both in recorded and online format), Iranian psychologists in the diaspora respond to people's questions about their relational challenges, including marital and family problems, using psychological techniques drawing from systemic, cognitivebehavioral therapies, as well as acceptance and commitment therapy.…”
